TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, PARKER MOODY, of Gloucester, in the county of Essex, and State of Massachusetts, have invented a new'and useful or improved Hawse-Pipe oruGruide;A and I do hereby declare the same to be fully described in the following specification, and represented inthe accompanying drawings, of which- Figure 1 is a top view. v

Figure Q, a'longitudinal section.

Figure 3, a front end view; and

Figure 4, a side elevation of one of such hawse-pipes.y

The hawse-pipe Aas ordinarily made for insertion in a vessels bow has but one friction-roller, which Ais arranged in the base of its mouth. This roller is te receive the bearing of the hawser orchain cable and ease it along during the process of heaving the anchor. When, however, the processof heaving the anchor or thc taking in of its hawser-cable or chain commences, as well as for some time afterward, the vessel is usually at such a distance from the anchor that the inclination of the hawser or chain to the horizon becomes very little. This will cause the chain or hawser to be elevated oil' the friction-roller and to run on the inner surface of the guide-tube, thereby generating much friction thereon, more or less detrimental to the cable, as Well as productive of addi--l tional resistance to be overcome by the sailors at the windlass. To prevent this friction, or to ease the cable while being taken in, and especially previous to the vessel being drawn so near to the anchor as to cause the cable to bear on the mouth-roller of the hawse-pipe, I form within the bottom of the haWse-pipe, and at a short distance in rear of its mouth-chamber, a recess, and place therein an auxiliary friction-roller to extend out of thel recess a short distance, and be so applied to the recess as tobe capable of supporting and being freely revolved by the cable while the latter may be in the act of being taken in. I-n the drawings- A denotes the hause-pipe or guide, and B its mouth or mouth-piece. The guide is usually a semi-tube or a whole tube extending backward from an arched mouth-piece, B. Within the lower part ofthe mouth-piece B is a recess, a, to receive a friction-roller, C, tc revolve freely on a pin, p, extending through the mouth-piece and the said recess. The auxiliary recess and friction-roller are shown at b and D ,as arranged square to or at right angles to the axis of the tube or hawse-pipe A. The auxiliary roller is to revolve on a spindle or pin, e, going through the chamber b, and held in place by dove-tailed plates d d, inserted in dove-'tailed recesses e e made in the sides of the hawse-pipe. Each of the chambers a b is provided with a passage,f or g, leading downward out of it, such being for the discharge of any water which may enter the chamber. The discharged passage of the auxiliary chamber isled horizontally or thereabouts into that of the mouth-piece chambely-as shown at z, such being to enable thewn-ter, when flowing out of the rearmost chamber, to be discharged into the discharge-passage of theifrout chamber and thence into the sea. The mouth-piece, which is oblique to the axis of' such hause-pipe, has the roller C arranged at right angles to the axis of the mouth-piece in manner as represented. Thus the axes of the two rollersI are out of parallelism or are at acute angles with each-other. As both of these rollers are Aconcave rollers, or are to be formed as represented in the drawings, the auxiliary rollers will operate to centralize the cable on the front or mouth-roller while the cable is bearing thereon. The auxiliary roller is advantageous in other respects. I do not claim a hawse-pipe as provided with a single frictiona roller arranged in the base of its mouth-frame, bnt- What I do claim, is the arrangement and combination ofthe auxiliary concave roller D, and its chamber b, with the hawse-pipe A, its oblique month-piece B, 'and the concave friction-roller C arranged in such mouthpiece, substantially as specified.

I also claim the combination and arrangement of the dove-tailed plates d d, and recesses e e, with the hawsepipe and its auxiliary roller D, and roller-chamber b, as described.

I also claim the construction of the roller-chambers with discharging passages -fg h leading therefrom and communicating as describedA PARKER MOODY.
